Make sure you restore your iPhone entirely as Bitewound said, preferably using iTunes, but also remove the sim card. Which iPhone is it? Depending on the iPhone, the sim card slot is located in a different location.

You can remove the sim at anytime. Just don't keep it in there when you sell it.

You can restore to factory settings using iTunes, and then remove the SIM card. The sim slot should be on the left side of the iPhone 4. As the Internet says, since they didn't give us iPhone 4 users a sim removal tool, you can use a paper clip edge and put It in the hole and it'll pop out. Remove sim and then put the tray back in

But when he/she gets my iPhone there carrier they give them a SIM card?
I always thought that when you erase the phone and settings you erase the SIM card to!
